The formula is supposed to "wear evenly" with "megawatt colour" and have a "tingly, cooling sensation" that makes lips "fuller." The coverage ranged from shade to shade, though most were fairly pigmented, and some seemed more multidimensional than others (they seemed just shimmery/pearly). Some shades applied evenly while others were more uneven or pulled into lip lines.
The finish had a lot of shine and shimmer, so any unevenness/settling wasn't as apparent in person as it might appear in close-up photos. The consistency was smooth as it applied and developed a lot of tackiness within a minute or so of application, and the tingling lasted noticeably for 20-25 minutes on me. The glosses lasted between four and five hours on me and were comfortable to wear but was mostly non-drying.
They have a sweet, mint scent and subtle tingle and almost seemed to have a slightly sweet taste, but I couldn't tell as I felt like I was breathing in the sweet mint a bit from the scent alone.
